Patented Nov. 24,, 1931 UNITED STATES- PATENT OFFICE SHOE Application filed February 20, 1931.

My invention relates to a welt shoe having an elastic outer sole composed of rubber or a rubber like composition, and having a molded bottom filler of the same material on its fore part supporting the fore part of the inner sole, the filler increasing the thickness of the fore part of the outer sole, the margin of the filler being spaced from the margin of the fore part of the outer sole by a seat for the 1 welt.

The chief object of the invention is to provide a welt shoe including inner fasteners such as the usual inseam stitches uniting the welt to the upper and inner sole, outer fasteners such as the usual outseam stitches, and

supplemental rigid fastening means associated with the marginal portion of'the filler and uniting the outer sole and filler to the inner sole, the latter being of practically inextensible material such as leather, such supplemental fastening means reinforcing the connection between the weltand the fore part of the outer sole, and preventing the outer sole, which is extensible, from being stretched or extended lengthwise by fiexure of the shoe caused by walking. such extension being liable to cause abnormal protrusion of the toe end of the outer sole from the toe end of the upper, and detachment of said toe end from the welt.

Other objects will appear hereinafter.

Of the accompanying drawings forming a part of this specification,.

Figure 1 is a top plan view of an outer sole of a shoe embodying the invention showing elements of supplemental fastening means.

Figure 2 is a bottom plan view and Figure 3 an edge view of thesole shown by Figure 1.

Figures 4, 5 and 6 are fragmentary sectional views each showing a portion of the outer sole and filler, said figures showing elements of the rigid supplemental fastening means, and illustrating the method of providing the outer sole and filler with said elements.

igure 7 is a section on the plane indicated by line 77 of'Figure 8.

Figure 8 is a fragmentary longitudinal sectlilon through the toe portion of the completed s 0e.

Figure 9 is a partial side view of the shoe Serial No. 517,340.

showing portions of the upper, inner sole, filler, and outer sole, in longitudinal section.

Figure 10 is a fragmentary perspective view showing, partly assembled, the toe portions of the inner sole and the outer sole with r its filler.

Figure 11 is a top plan view of the outer sole on a reduced scale showing more elements of the rigid supplemental fastening means than are shown by Figures 1 and2.

The same reference characters indicate the same parts in all of the figures.

In the drawings 1 designates the composition outer sole to the fore part of which is inseparably connected a molded composition filler 2 having an edge face 2a spaced inwardly from the margin of the fore part by a seat for the welt 10, said edge face being preferably perpendicular to the welt seat. The welt is united by inner fasteners, here shown as inseam stitches 14 engaged with the Welt, passing through the marginal portion of the upper, and engaged with a lip projecting from one side of the inner sole 7. lip is formed by two flaps 8 and 9 integral with the inner sole and bent outwardly from one side thereof, the inner flap 8 bearing on the edge face 2a of the filler as Figures 7 and 8.

The welt is united as usual to the outer sole by outer fasteners, here shown as out seam stitches 16.

I prefer to embody the rigid supplemenshown by as usual to the upper 11 In this instance the v tal fastening means associated with the mar- 35 ginal portion of the filler and uniting the outer sole and filler to the inner sole, in rigid washers embedded in the marginal portion of the filler, and headed nails 20 driven through the tread face of the outer sole through said washers and into the inner sole 7, and clinched on the latter as shown by Figures 7 and 8, the heads 21 of the nails abutting the washers so that the washers and nails collectively constitute a rigid connection between ers and clinched on the inextensible inner :06

by the tendency of the fore part of the exiil tensible outer sole to stretch lengthwise or creep forward when the wearer is Walking. Such stretching or extension is liable to cause the detachment of the toe portion of the outer sole from the fasteners 16 and thus practically ruin the shoe. Such detachment is prevented by the positive connection of the toe portion of the filler with the toe portion of the inner sole by the described rigid attaching means.

It is obvious that the number of Washers in the toe portion of the filler and the number of nails engaged therewith to perform the function above described may be varied.

Figure 11 shows a row of Washers 25 embedded in the marginal portion of the filler and extending about the same, these washers engaging a row of-headed nails driven into the inner sole and clinched thereon, the nail heads abutting the washers. The row of washers and nails constitute a more extended embodiment of rigid supplemental fastening means adapted to prevent the fore part of the outer sole and filler from being extended lengthwise and from being detached from the welt.

The top surface of the filler includes a marginal portion 20 inclined upwardly and outwardly from a fiat central portion to the edge face 2a, and increasing the thickness of the marginal portion of the filler. The above described washers, including the Washers 4 and 5 are embedded in the thickened marginal portion of the filler and under the inclined portion 20, so that they are separated from the tread face of the outer sole by an adequate thickness of Wear-sustaining material. The inclined portion 20 is adapted to shape and support the marginal portion of the inner sole fore part, said marginal portion conforming to the inclined portion as shown by Figures 7 and 8. The washers 25 at the toe portion of the filler function like the washers 4 and 5. The rear end of the filler is adjacent the ball line of the outer sole as designated at 3 and preferably has an inclined transverse end face 21) forming a seat or abutment for the forward end of a shank stiffener as shown by Figure 9. One of the washers 25 may be embeddedin the filler under the end face 26.

In embedding the washers in. the filler while the material thereof isplastic I sup-'- port each washer on a supporting pin Whirh forms a nail receiving bore 17 in the outer sole and filler. The bore does not extend to the tread face of the outer sole, and its position is indicated by a pin which forms marking indentations 18 in the tread face enabling the nails to be driven accurately into the washers. I

In Figure 4 the condition of the outer sole, filler and one of the washers is shown without the nail. When the nail is being driven its point strikes an anvil 22 designated by dotted lines in Figure 5, and is clinched as shown by Figures 7 8 and 9. It will be understood that when the nail is driven until its head abuts the washer its point is clinched by the anvil 22, although not so shown by Figure 6.

After the nail is driven the elastic material of the outer sole through which the nail head passes to the washer expands and sufficiently closes the hole made by the nail head.

The essence of the invention resides in the rigid connection provided b the nails and washers between the toe portlons of the filler and inner sole, the washers being essential elements of this connection. Headed nails driven into the filler and engaged with the inner sole, no washers being provided, do not constitute a rigid connection adapted to prevent the endwise creeping or stretching of the outer sole and filler. The usual inseam and outseam stitches are relatively flexible and do not prevent the forward lengthwise creeping or stretching of the fore part of the outer sole, so that a shoe without the rigid washers and otherwise constructed as set forth, has a fatal defect because a brief period of wear causes the toe portion of the outer sole to creep forward, protrude abnormally from the toe portion of the upper, and destroy the connection between the toe portions of the outersole and welt. This defect is prevented by the rigidity of the connection between the filler and inner sole provided by the nails plus the washers.

The construction of outer sole according to my invention permits any desired design to be worked into the tread surface of the outer sole, such as various ornamental representations desirable in sport and golf shoes. That is to say, the filler which is molded integral with the outer sole provides the required thickness and the required support for the inner sole, despite the fact that the thickness of the outer sole is reduced by the ornamentation.

The increased thickness of the fore part of'the outer sole due to the filler, enables the washers to be located above the wear sustaining portion of the fore part.

I have found that the construction herein is highly practical and permits rapid and inexpensive manufacture on a quantity production basis.

While I have described my invention in certain preferred embodiments I desire that it be understood that modifications may be made and that no limitations upon my invention are intended other than are imposed bv the scope of the appended claims. v
